Aaron Smith may have misled All Blacks bosses in sex scandal

A series of text messages has been released that appear to show Aaron Smith has been lying to cover his tracks, in regard to an incident in which the rugby star was caught with a woman in an airport toilet last year.

If genuine, the messages show Smith convincing the woman to lie in a legal document, misleading his coach and attempting to deceive his partner.

If genuine, the newly released messages show Smith convincing the woman to lie in a legal document, misleading his coach and attempting to deceive his partner.

The All Blacks star allegedly had sex with the woman in a disabled toilet at Christchurch Airport in September 2016.

He claimed it was a one-off incident and apologised for his "huge error in judgement".

But the woman told the Daily Mail Australia that she was involved in an affair with Smith for two years.

"When we got caught he lied about what had happened and asked me to stick to the story he had told his new girlfriend and coach, which essentially put the blame on me," she told the Daily Mail Australia.

"I was definitely the scapegoat so that he could get out of it, he threw me under the bus to try and save his own career."

She said frustration with her portrayal by Smith and All Blacks management led her to release the messages.

It's bad timing for Smith and the All Blacks, ahead of their Bledisloe Cup test against the Wallabies on Saturday night.

The extensive Facebook conversations appear to show Smith and the woman initially planning their liaison at the airport using sexually explicit language.

After news of the scandal breaks, the tone of the messages changes, with Smith allegedly laying out a story in which the pair chatted and "nothing happened."

"What I have said is u message me, to come for a chat. I came for a chat, nothing happened in there. I said I got all flustered and left OK. But if anyone ask you something, please say that. Only my coach been hit up ... I'm hoping nothing goes to media OK. Please stick with this, I'm hoping u won't get brought up OK," the screenshot message says.

In a follow-up message, the person identified as Smith attempts to convince to woman to lie on an affidavit - a document for use as evidence in the court.

In repeated messages, Smith tells the woman to delete the messages and to stick to the story.
